Description

Technical Field

[0001] The utility model relates to the technical field of garage lower limit stops, in particular to a wire rope driven lifting and transversely moving mechanical garage lower limit stop device. Background Art

[0002] The lower limit stop device of the wire rope driven lifting and transverse moving mechanical garage is mainly used to ensure that the car stops safely and accurately at the designated position during vertical lifting or transverse movement in the mechanical garage system. This device usually includes a lower limit switch and a stop block, which can stop or slow down the movement of the garage lifting mechanism through induction or mechanical triggering when the vehicle reaches the set lowest floor or parking space, so as to prevent the vehicle from exceeding the predetermined position and causing collision or damage.

[0003] At present, there is only a wire rope blocking the falling path of the lower limit counterweight rod, without considering the situation that the wire rope is too much or disconnected, which poses a safety hazard. Therefore, a wire rope driven lifting and transverse moving mechanical garage lower limit stop device is proposed to solve the above problem. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a lower limit stop device for a wire rope driven lifting and transverse moving mechanical garage, aiming to improve the problem in the prior art that the wire rope is too much wound or disconnected, which poses a safety hazard.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A lower limit stop device of a wire rope driven lifting and transversely moving mechanical garage comprises a support frame, a fixing plate is detachably connected to the top left end of the support frame, a limiting wheel 1 is rotatably connected to the inner wall of the fixing plate, a lower limit counterweight rod is fixedly connected to the right end of the limiting wheel 1, a limiting assembly is arranged at the front end of the lower limit counterweight rod, a wire rope is arranged outside the limiting wheel 1, a fixing frame is fixedly connected to the top right end of the support frame, a lower limit stop rod is detachably connected to the front end of the fixing frame, and a needle travel switch is fixedly connected to the left end of the fixing frame;

[0007] Specifically, the needle-type travel switch is opened by moving the lower limit counterweight rod pulled by the wire rope, and when the wire rope breaks, the lower limit stop rod is used to limit it to prevent the lower limit counterweight rod from falling, thereby improving safety.

[0008] As a further description of the above technical solution:

[0013] Specifically, the needle type travel switch can be turned on by the limit counterweight rod contacting the needle type travel switch.

[0014] As a further description of the above technical solution:

[0015] The steel wire rope passes through the top of the limiting wheel 1 and the bottom of the limiting wheel 2 in sequence;

[0016] Specifically, the limiting wheel 1 and the limiting wheel 2 can be pulled by the wire rope to achieve lifting.

[0017] As a further description of the above technical solution:

[0018] The bottom of the lower limit counterweight rod is in contact with the top of the lower limit stop rod;

[0019] Specifically, the contact between the lower limit counterweight rod and the lower limit stop rod is to provide physical support when the wire rope breaks to prevent it from falling.

[0020] As a further description of the above technical solution:

[0021] The fixing plate is made of steel and is mounted on the top of the support frame by bolts;

[0022] Specifically, this enables the fixing plate to provide additional support and facilitate installation and removal via bolts.

[0025] Specifically, this enables the fixing frame to provide additional support and facilitate installation and removal via bolts.

[0027] The rear end of the lower limit counterweight rod is in contact with the front end of the fixing frame;

[0028] Specifically, in this way, the lower limit counterweight rod will be restricted on the surface of the fixing frame.

[0029] The utility model has the following beneficial effects:

[0030] In the utility model, when the wire rope breaks during operation, the lower limit counterweight rod will also fall uncontrollably due to the loss of tension support. At this time, the lower limit counterweight rod is blocked by the lower limit stop rod, thereby preventing the uncontrolled falling of the platform, enhancing the safety of the system, and significantly reducing potential safety hazards, ensuring the efficient and safe operation of the mechanical garage.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Reference Figure 1-Figure 2 The utility model provides an embodiment: a lower limit stop device of a steel wire rope transmission lifting and transverse movement mechanical garage, comprising a support frame 1, a fixing plate 2 is detachably connected to the left end of the top of the support frame 1, the fixing plate 2 is made of steel, and the fixing plate 2 is installed on the top of the support frame 1 by bolts to ensure the stability and durability of the entire structure. The fixing plate 2 can be easily disassembled and installed by bolts, which is convenient for maintenance and replacement of the equipment. The inner wall of the fixing plate 2 is rotatably connected with a limiting wheel 3, and the limiting wheel 3 can be limited by the fixing plate 2. The right end of the limiting wheel 3 is fixedly connected with a lower limit counterweight rod 4, and the lower limit counterweight rod 4 adopts a weighted design, and its weight helps to maintain the balance and stability of the system.

[0037] A limiting component is provided at the front end of the lower limit counterweight rod 4, which is used to accurately control the position and tension of the wire rope 6. This limiting component is suitable for vehicles of different sizes and weights to ensure the stability and safety of the lifting platform. A wire rope 6 is provided on the outside of the limiting wheel 3. A fixing frame 7 is fixedly connected to the top right end of the support frame 1. The fixing frame 7 is made of steel and is installed on the top of the support frame 1 by bolts, so that the fixing frame 7 can provide additional support for subsequent components and is convenient for subsequent disassembly and maintenance by bolt installation. The rear end of the lower limit counterweight rod 4 contacts with the front end of the fixing frame 7, which will limit the lower limit counterweight rod 4. The front end of the fixing frame 7 is detachably connected with a lower limit stop rod 8. The design of the lower limit stop rod 8 allows it to prevent the lifting platform from further descending when it reaches the specified position, effectively preventing accidents caused by excessive movement. A needle-type travel switch 9 is fixedly connected to the left end of the fixing frame 7.

[0038] The limiting component includes a limiting wheel 2 5, the rear end of which is rotatably connected to the right side of the front end of the lower limit counterweight rod 4, the outside of the limiting wheel 2 5 is in contact with the outside of the wire rope 6, and the wire rope 6 passes through the top of the limiting wheel 1 3 and the bottom of the limiting wheel 2 5 in turn. This method of passing enables the wire rope 6 to form an effective guide and tension control, thereby ensuring the smooth and precise operation of the lifting mechanism. The bottom of the lower limit counterweight rod 4 is in contact with the outside of the needle travel switch 9. This contact triggers the action of the switch, thereby controlling the stop position of the lifting platform to ensure safety. The bottom of the lower limit counterweight rod 4 is in contact with the top of the lower limit stop rod 8. This contact ensures that the lifting platform can stop stably when it reaches the set lowest point, avoiding structural damage or vehicle collision caused by excessive descent.

[0039] Working principle: When the platform starts to descend, the tension of the wire rope 6 guides the lower limit counterweight rod 4 to move downward. On its descending path, the counterweight rod first contacts the pointer of the needle travel switch 9, which is responsible for monitoring and controlling the descent limit of the platform. Due to the problem that the wire rope 6 may be too much, the lower limit counterweight rod 4 may continue to slide after the switch is triggered for the first time, thereby losing contact with the pointer of the travel switch. In order to prevent the vehicle loading platform from falling out of control, an additional lower limit stop rod 8 is designed. The stop rod is located below the lower limit counterweight rod 4 to prevent it from sliding down excessively, ensuring that the needle travel switch 9 effectively controls the stop position of the vehicle loading platform during the entire process. If the wire rope 6 breaks during operation, the lower limit counterweight rod 4 will also fall out of control due to the loss of tension support. At this time, the lower limit counterweight rod 4 is blocked by the lower limit stop rod 8, thereby preventing the vehicle loading platform from falling uncontrollably and enhancing the safety of the system. Through this structural design, the device can provide stable and reliable lifting operations while significantly reducing safety hazards, thereby ensuring the efficient and safe operation of the mechanical garage.
